Crosshairs are a tool that displays the x- and y-values of any point on a graph, such as on a scatterplot. As you move the mouse pointer, the crosshairs location and coordinates update. Crosshairs are a quick and easy way to explore data on your graph.
For the 3-dimensional contour plot, crosshairs display x-, y-, and z-values.
You can display crosshairs when you create a graph that has x and y scales, including categorical scales. Crosshairs are not available on the pie chart, dot plot, marginal plot, 3D scatterplot, or 3D surface plot.
You can use crosshairs to provide exact locations for users to insert annotations, such as polylines, on a graph. For more information, go to Annotation shapes, text, and markers.
A flag is at type of graph annotation that displays the precise x-, y-, and z-values for any point on a contour plot. Use a flag to determine the response value for a specific combination of factor or component levels. Flags are permanent annotations on the graph; therefore, they are useful for reports and presentations.
You can plant a flag at any point on a contour plot.
After you plant a flag, you can edit it.
